Manslaughter charge for man over NSW crash

A man who allegedly caused a fatal fiery eight-car crash in Sydney's southwest has been charged with a string of offences including manslaughter.

Robbie David Crowley, 26, did not appear in Parramatta Bail Court on Sunday and was represented by his lawyer over the Good Friday crash, which killed a teenage Uber passenger and seriously injured four others.

He has been charged with 13 offences including manslaughter, aggravated driving occasioning death and negligent driving.

Crowley, who remains in hospital, didn't apply for bail and it was formally refused on Sunday.

Police allege Crowley was speeding in his Commodore before it veered into oncoming traffic on Friday evening at Woodbine, causing the "unbelievable" smash that involved seven other vehicles.

A 17-year-old boy travelling in an Uber was killed and five others were taken to hospital.

A 57-year-old male driver and his passengers, two men aged 19 and 20 and an 18-year-old woman, have had surgery and remain in serious but stable condition.
